I 1 4 f i is-e planAnew oijthe egpar'z tusgm 9 Patented Feb; 25, 193, I i f 1 157485 Q position for grinding a pair of railway car wheels;

Fig. 2 is a side elevation of the apparatus shown in Fig. 1;

Fig. 3 is a detail view in elevation showing the method of securing the apparatus to the railway track;

Fig. 4 is a longitudinal sectional view through the journal box of a railway car showing our improved device for centering the wheels and holding them in position for truing up when raised clear of the track; and

Figs. 5 and 6 are an end and side elevation, respectively, of the centering device removed from the journal box.

Referring now to the drawings fora better understanding of our invention, we "show" a pair of car wheels 10 and 11, the-car wheelshaving journals 12 and 13', the journals being provided with the usual ournal boxes 14 and 16. As is well understood the journal boxes are firmly held in place by the truck frame, a typical illustration of which is-shown in 2. The truck frame may comprise an upper bar 17, a lower bar18 and a pedestal tie bar 19, all of said bars being secured to said journal boxes by pedestalbolts 21 and For brevity of description, the entire car truck is not shown, because its construction forms no part of our invention and may differ very widelyin design according to the service for which it is intended. It is understood and well known, that the weight of the car, a fragmentof which is shown at 23 in Fig. 2, is transmitted to the journal through the truck frame, the journal box and suitable bearings such as brasses, shown at 24 in Fig. 4, and brass retaining membersor wedges such. as 26. The end of the journal box, where the journal enters, is provided with an opening 27, somewhat longer than the journal so as to permit wear of the bearing 24 without engagement, of the journal with the journal box, and also to permit the ready application and removal of the box from the journal. Wheneverit is desired to remove a bearing from a journal box, a jack, such as 28, is placed beneaththe journal box or the pedestal tie bar 19 and the box is raised so as ;to free the bearing. 7

Our improved machine for truing up car wheels such as have just been described, com- 7 prises a base member 31 having a frame embodying cross rails 32 and 33-adapted' to lie across the parallel rails of the railway track.

.The base 31 may be supported in any suitable manner from the rails 32 and 33. For convenience in handling, we show the-base 31 as mounted on flanged pairs of wheels 34 and 36. With this arrangement the rails 32 and 33 may first be laid across the track and the machine properly placed upon the,

rails 32 and 33 and rolled to position. When in position, the wheels may be held fromfurther movement by suitable stops 37 and 38.

web 44 of the opposed railway rail.

hooks over the head of one of the railwayrails and engages the web 41 thereof. At the other end of the rails 32 and 33 a flange member 42 .is welded to the'ends of the rails 32 and 33 and is provided with suitable tightening screws43 adapted to bear against the In this manner the frame of the machine may be rigidly secured to, the railway track.

Mounted on the base member31 is a frame Carried by the pivoted moved transversely ofthe frame and of the wheels 54 and 56 causing them to traverse the treads of the wheelslO and-11.

Mounted on the base member 31 and pivoted thereto on the side opposite the shaft 51 is a screw 63, cooperating-with a pivot nut 64 carried in a strap 66, the latter being secured to the pivoted frame 46. The pivotal connection of the screw 63 with the base 31 is formed with a swivel connection 67. A

handle 68 is provided on the screw 63 wherej 'by it may be turned to the right ,or left and the shaft 51 is a sprocket 73, connected to the sprocket 72 by a chain 74. In this manner, the shaft 51 is rotatedat the same speed as the motor71 andin the same direction. The sprocket 73 is splined to theshaft 51v and .is provided with a collar 7 O. The collar 70 is held from longitudinal movement by-a member 65 secured'to the pivoted frame 46.

Directly connected to the motor 74 is a relatively small gear 76 meshing with a'larger gear78, the latter being mounted on a shaft- 79 journaled in suitable bearings 81 and 82 2. v turning car wheels when ralsed clear of the V O th shaft 9:--i;s nneal-y small f spmek thed :83, Fl w ll he obser ed tha with the g a rai s wn,z he s a tflfi and sprock .83- are a sed. t 1 ebat :a diree tion opposite o hat of: the motor and .at 1 a :liowerspeed In :order to transmit'imotionlfrom the sprocket 83 .tothe wheels 10 and 1 1, w11en thgeyg are, {raised clear :of the :rails and supported and centered in a manner to bweidescribedmore particularly herelnafter, we provide ajdividedspireocke't 84 adapted to be clamped, as by means of bolts 86 torthe car wheel axle '87, and connected to the sprocket 83 by a sprocket chain 85.. The'sprocket 84:

. is -made 'much larger in diameter than the sprocket 88 whereby the speed of rotation of the wheels 10 and 11 is less than that ofthe sprocket 83, the object being to impart a much slower rotative movement to the wheels lOrand 11 than the speed of the motor 1 and in a direction opposed to the direction of ro- J tation of the grinding wheels 54 and 56.

With the apparatus so far describeditwill be observed that we have provided means for I rails and for grinding the wheels while being Zen turned. It will be obvious however to those skilled in the .art thatifno means are'provided for holding thewheels firmly centered during rotation that a given point on the periphery thereof would not describe 'a true circle and, when the grinding operation was completed the trea'dof the wheels would not be truly concentric with respect to 'the journal. We have accordingly provided a simple a effective means for accomplishing this im- I portant purpose. As is well understood -all f I car wheel journals are provided, when made,

with centering holes in the ends thereof such as is shown at 91 inFig'. 5, the purpose of these centering holes beingto mount'the journals 1 and wheels in a lathe or'othersuch apparatus when being turned up for service. We utilize ing screw 92, this latter'member being provided, with threads93 coactin'g with similar these centering holes to coact with a-center- "threads formed in thebody portion of a supporting member'94c. The bodyportion of the supporting member 94 is provided with a slot 96 adapted to hook over the edge of a journal boX.. A lower depending portion 97 of the supporting member is adaptedv to be entered I in'the journal box beneath the end of the j ournal and bear against the bottom of the journal box in Orderto support the wheel. order to accommodatejthe centering device to'journalboxes of various depths a pair of. adjusting screws 98 are provided in the depending portion 97 whereby the body portion 94 and centering screws 92 can be set at such an angle as to cause the centering screw to'be coaxial,

' when raised with its cooperating journal.

When a pair of wheels are to be ground in place, the machine is placed adjacent to the hviii hrthe r-ingeserew "journal b025,. on y she jack wh elsawe enteringde ises a e'hoe ed V 9 the e e openendeithejournalhm .92-: etr eted. The
